dill: stop redrawing the prompt & cursor
No longer inserts newlines or redraws the prompt post-print, pushing this responsibility down to drum where it belongs. Additionally, separates the flow for dill's own output, from that of the console application. This lets us keep the desired behavior for now, and will ease reworking in the future. Last-printed-line and cursor position are still kept around in dill state, in order to respond to the relevant scry endpoints. These should either be refactored to scry into the underlying console app, or be removed entirely in favor of %hey.
